Anorthoclase and Cordierite Chemical Formula
While comparing Anorthoclase and Cordierite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Anorthoclase and Cordierite chemical formula.

Anorthoclase and Cordierite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anorthoclase and Cordierite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anorthoclase and Cordierite Optical Properties during the identification of gemstone. Specific gravity of Anorthoclase is 2.57-2.66 whereas that of Cordierite is 2.57-2.66.
